CONVECTION
a. Go to the Side Legend in the Display Window. Check the box
next to omega and move ahead to 12z (8 AM
EST) on January 29th by hitting the next image button of the toolbar (next
to the play button in the top right corner of the display window).
Isosurfaces of upward motion (-0.4 Pa/s) will
appear in blue. The following image is what the bundle should look like
once you have checked the box next to Omega. You will notice an isosurface
to the east of Lake Ontario. Strong upward motion is an important factor in the formation of convective snow
bands which can result in limited areas of intense snowfall. Also, convective snow
bands develop and are enhanced by frictional convergence and orographic lifting
over an inland of the leeward shore.
